Hi, this is a pair of well made speaker platforms. The bases are 10.75 by 11.75 inches, and the speaker platforms are 7.75 by 9.25 inches. They have felt on the bottom to protect your floor, and they have foam along the border of the platforms to rest the speakers on. The speaker platforms are 6.5 inches high at the back, and 7 inches high at the front, to give your speakers a slight upward tilt. Just $15, or will consider serious offers. Please email, call, or text to come see them, thanks.
